What are sweepstakes slots?

Sweepstakes slots are casino-style slot machines that are available at social casinos. Players can access these games using virtual currencies like Gold Coins (GC) and Sweepstakes Coins (SC) without spending a dime.

It’s crucial to note that despite not operating using the standard casino model that requires players to access games using actual money, sweepstakes slot machines function similarly to their conventional kinds. They feature the same rules, designs, and gaming experiences.

Moreover, they are often from the same developers. For instance, a popular game like Sweet Bonanza at a regular casino is the same at a sweepstakes site. The significant difference is that sweepstakes casinos allow people to play them for free using virtual coins, while regular casinos require their players to make a payment to play.

That means when making the best slot machine RTP list, it is equally applicable to sweepstakes casinos. And that is what this post is about.

What is RTP, and why is it important in casinos?

RTP means “Return to Player.” It is the percentage representation of how much house edge a casino has. That is, how much profit a casino is projected to make from the total amount players use on a particular game. You can view it as the operator’s level of fairness in its gaming outcomes.

For instance, if a casino game has a 99% RTP rate, it means the operator expects a 1% profit from every spin on that game. That means players have a good advantage at such a casino.

RTPs are crucial to modern gaming because they help determine that players are not cheated through manipulated or unfair gaming outcomes. The lower the RTP rate at a casino, the higher the brand’s advantage.

So, before playing games at any casino, it’s important to check its RTP rates to determine your winning possibilities. However, you should note that a 99% RTP rate doesn’t mean you have a 99% chance of winning. RTPs don’t predict or influence gaming outcomes.

Best RTP slot machines to play at social casinos

The sweepstakes gaming market is saturated with thousands of casino-style slot games, each with its unique features and offerings. Here is a breakdown of the top 10 high RTP slot machines I’ve found over the years in no particular order:

Ugga Bugga

First on my list of slot machines with the highest RTP is Ugga Bugga. The game has different variants built by Playtech and Williams Interactive. However, one thing they all have in common is its high RTP of around 99%.

During my review, I focused on the Playtech version, which features 10 reels and 10 paylines. That means you’ll get 10 chances to land a winning combination upon every spin, providing you with the chance to get decent returns.

Like many casino slot machines, it has a jungle theme that gives players a sense of adventure. However, it does not have many bonus opportunities. I discovered there are no bonuses when playing Ugga Bugga, which is somewhat disappointing.

The game strives to make up for this downside with its hold feature and high RTP. However, if you’re keen on playing with bonus boosts, Ugga Bugga may not be the best for you. 

Mega Joker

Mega Joker is another top choice when looking for the best RTP slot machines at a sweepstakes casino. Like many other slot games, brands like Novomatic and NetEnt have games with the same name. However, my focus is on the one from NetEnt because of its solid standing in the casino gaming industry.

The Mega Joker game from NetEnt has 5 reels, 40 paylines, and a progressive jackpot. So, there are numerous opportunities to win more coins if you land a great combination.

I love the game because it’s a classic slot machine with a super high RTP of 99%. Another exciting feature is its graphics that simulate the land-based casino experience, which gives players the best of the classic and modern touch.

Regarding bonuses, Mega Joker doesn’t have so many options. There is a progressive jackpot that you can trigger if you get 3 joker symbols in a row. You can also play in the Supermeter mode to improve your potential coin returns.

Blood Suckers

As the name suggests, Blood Suckers is a vampire slot game that offers players a gothic gaming experience when playing. So, if you like a bit of horror and chaos, you’ll find the game thrilling.

The game is powered by NetEnt and features great designs and video quality. With 5 reels and 25 fixed paylines, and a high RTP that stands at 98%, Blood Suckers delivers various opportunities for remarkable coin returns.

Since its paylines are fixed, all are active, so you don’t need to choose paylines manually when playing. All you have to do is enter the amount of GC or SC to play with and spin the reel to potentially land winning symbol combinations on the paylines.

Another reason I rate the game as one of the best RTP slot machines is its bonus features. The game has bonus rounds with wild, scatter, and bonus symbols. If you land these symbols, you’ll get bonus offers such as free playing coins and bonus spins to improve your chances.

Starmania

Though Starmania is not a very popular slot game, it makes my best slot machine RTP list because of its high 98% RTP rate. Besides the design, I love the space-themed design that makes players feel at home among the stars.

The game is from NextGen Gaming, featuring 5 reels, 3 rows, and 10 fixed paylines. Like Blood Suckers, all its paylines are active, so you don’t have to set any manually.

While playing, I found it impressive that you can easily change your playing amount between spins, making it possible to increase or reduce the amount based on how the game is unfolding. You also need to match 3 or more symbols to land a winning combination.

Despite its low volatility, you can win up to 500x your playing amount on Starmania if things go your way. There are also wild and scatter bonus symbols that can help you land free spins and other bonuses.

However, Starmania is quite old now, so if you want a strictly modern casino slot, it may not be the best option.

Book of 99

If you love history, you’ll fancy the Book of 99 slot game from Relax Gaming. The exciting game has various features, including book collections, Greek gods, and mythology inspired by characters like Cyclops and Homer.

The game has five reels and ten paylines, with an RTP of 99%, which makes it stand out among many “book” slot games, including Book of Ra. When playing, I discovered that the game’s book collection is a powerful bonus feature.

It serves as the game’s wild and scattered symbols. As a wild symbol, the book can help you create a winning combination. However, landing 3 or more combinations isn’t really significant because there’s no scatter win. The features you will find are bonus spins and special expanding wilds during bonus rounds.

Moreover, the game belongs to an overcrowded category, and the 99% RTP is achieved in the long run. That means it may eventually get boring because of its long-base game sessions.

Jackpot 6000

Modern players will fancy Jackpot 6000 because of its perfectly executed mobile-optimization feature. However, it remains a classic slot game from NetEnt, which was evident in its fast load speed and sleek design. Everything about the game shows its simplicity, making it a decent choice for beginners.

The 3-reel slot game has 5 fixed paylines, so there aren’t many ways to win big. Additionally, there are no special or bonus symbols like scatter or wild. However, it stands out from other NetEnt games by using only symbols. There are no letters and numbers that you’ll typically find in many video slots from the developer.

The only notable bonus I observed when playing the game was the “Mystery Win” I got at some point. This was only possible in the Supermeter mode, and I received some free playing coins. Though the coin reward ranges from 10 to 6000, I coincidentally struck a big jackpot and got 6,000 coins after landing 3 joker symbols on one of the 5 paylines.

However, the audio quality was underwhelming. I didn’t hear a sound until I got a win from playing. The quality of the background sounds could also be better.

White Rabbit Megaways

White Rabbit Megaways is another high RTP slot machine out there. The game features white rabbits in a wonderland, offering players an immersive experience as they strive to land the best winning combinations.

Besides the game’s theme, what makes it stand out is its high RTP rate of 97.72%. Notably, the Big Time Gaming slot boasts one of the highest RTPs among slots with the Megaways operational model.

Moreover, the game gives players 248,832 paylines, so you can easily find opportunities to improve your chances. The well-designed graphics and various bonus features are also a plus. These include wilds, scatter symbols, multipliers, and free spins that you can use to enhance your gaming experience.

There’s also a “Feature Drop” opportunity that allows players to purchase bonus spins during games. The cost isn’t fixed, but it is reduced when you land a Feature Drop symbol on the reels when playing. Before moving on, it’s crucial to note that the maximum you can win from the game is 25x your playing amount.

Guns N’ Roses

As the name implies, the Guns N’ Roses slot pays homage to the famous rock band with the same name. The game is from NetEnt, featuring 5 reels and 20 active winning lines.

What initially stood out for me when playing the game was the music. Since it’s a representation of the Guns N’ Roses band, it was exciting listening to a soundtrack of their biggest songs as I was playing. The crowd also cheers when you land winning combinations.

If you thought you’d seen slot features in the past, you’ve properly never met Guns N’ Roses. The game has plenty of features, including “Legend Spins” for wilds and bonus spins, the “Appetite for Destruction” wild feature, and a random multiplier called “Solo Multiplier.”

Other bonuses include Encore Free Spins and Crowd Pleaser, with multiple bonus spins and bonus games, respectively. However, Guns N’ Roses is a low-volatility game with a variance that may not suit high-risk players.

The Catfather

The Catfather is the penultimate slot on my list, and that’s because it’s another quality game with a high RTP rate of 98.10%. The game is from Pragmatic Play, a leading casino gaming developer. So, you likely have an idea of its impressive graphics, sounds, designs, and overall gameplay.

It’s important to note that The Catfather isn’t very popular, but that doesn’t take anything significant away from it. The game features 5 reels and 9 furry winning lines.

The game’s symbols are various cat species, including one in sunglasses and a baseball cap and another ginger cat with an eye mask on. But I discovered the most important cat is the one with a monocle, which offers bigger coin wins if landed. So, if you love feline animals, here’s the perfect game for you.

The game’s wild symbols are some little kittens in a box. You can also use scatter symbols to increase your chances. You’ll get 10 bonus spins from 3 scatters, and if you land 5 scatters, you get a 20x return. Moreover, there’s a 4x multiplier to boost your bonus spins even more.

Medusa Megaways

Finally, we are down to the last game of my high RTP slot machines list. Medusa Megaways is from SG Digital, with an RTP rate of around 97%. It is another slot game that takes players through a journey into ancient Greek mythology, and it features stunning visuals.

The game’s volatility is high, so you have to be cautious when playing to avoid large losses. Moreover, you can use bonus features like wilds, scatters, multipliers, and bonus spins to enhance your gaming experience.
